// 关于路由的一切用法，细节，横向，纵向比较，正反合

// const router = createRouter({
//   history: createWebHashHistory(),
//   routes
// })

// export default router

const fs = require('fs')
fs.watch('./', (ev, name) => {
  if(name){
    console.log(name)
  }
})

const http = require('http')
http.createServer()

const path = require('path')
path.resolve()


// export default 加了default只有一个，
// import  export 才是js难
